Enhance the Watchlist block (Bug #1516981)

Enhance the "Watched pages" block to configure it so as to
display changes relating to users' friends since their last
login of different time frame (e.g. last week, last month,
last quarter, last year, etc.).

behatnotneeded: Tests will be written later.
